- Ion Exchange Resin
It presents extremely high selectivity for Ca²⁺ during brine purification. It features excellent physical and chemical strength with a low breakage rate after long-term operation. The ion exchange selectivity is listed as follows: Fe³⁺> Hg²⁺> Cu²⁺> Pb²⁺> Ni²⁺> Cd²⁺> Zn²⁺> Co²⁺> Fe²⁺> Mn²⁺> Ca²⁺> Mg²⁺> Ba²⁺>Sr²⁺>>> Na⁺
It is mainly used for brine refining, and can also remove and recover copper and heavy metals from electroplating wastewater.
